The Ministry of Land, Infrastructure, Transport and Tourism is promoting efficiency and sophistication. The information processing system 1 relates to a CIM, and is for making it easier to use information on the results of inspections and investigations or diagnoses of concrete structures.

The information processing system 1 includes various inspection devices 40, a server device (referred to as "server" in the figure) 10, a terminal device 30 (in FIG. 1, a notebook computer 30a and a tablet terminal 30b are exemplified), and inspections. It has a storage device 20 for storing measurement data and imaging data received from the device 40. The server device 10 and the storage device 20 are built on the so-called cloud 7. Therefore, the server device 10 and the storage device 20 are connected to the terminal device 30 and the inspection device 40 via a communication network. At least part of the communication network may be wireless.

In order to maintain the concrete structure, it is necessary to regularly inspect, investigate and / or diagnose the concrete structure, judge the necessity of repair, and review the repair plan. In addition, damage and deterioration of concrete structures include those that appear outside such as cracks and those that progress inside that cannot be seen from the outside, such as neutralization, hollowing, and corrosion of reinforcing bars. Inspection, investigation and / or diagnosis of concrete structures is carried out by measuring and imaging the damage and deterioration status of concrete structures using various devices. By combining the results obtained by using a plurality of types of devices in this way, the accuracy of inspection, investigation, and / or diagnosis of concrete structures can be further improved.

FIG. 9 is a flowchart showing an example of the operation of the concrete structure management device 100. First, the display processing unit 102 displays a three-dimensional image of the concrete structure on the screen (step S11). Next, the acquisition unit 104 acquires at least the first measurement result by the first measurement method and the second measurement result by the second measurement method in the concrete structure (step S13). Then, the display processing unit 102 superimposes and displays at least the first measurement result and the second measurement result on the screen (step S15).

A more specific processing procedure will be described below.
FIG. 10 is a flowchart showing an example of the operation of the concrete structure management device 100. First, the display processing unit 102 causes the display device 74 of the terminal device 30 to display a three-dimensional image of the concrete structure (step S101). Then, when the operator selects a certain place on the three-dimensional image, the display processing unit 102 accepts the selected position (step S103). Then, the display processing unit 102 specifies the structure ID, area, or division ID corresponding to the selected position (step S105).

Then, the display processing unit 102 reads the information corresponding to the area or the division from the management table 52, and determines which inspection information is stored from the inspection ID stored in the management table 52 (step S107). Then, the display processing unit 102 can display the inspection item in which the inspection information is stored in the operation menu (step S109), and allow the operator to select the inspection item to be displayed. When the operator selects an inspection item from the operation menu, the display processing unit 102 accepts the inspection item (step S109) and acquires the data ID of the inspection item associated with the area or division ID. The display processing unit 102 reads the measured value information associated with the data ID from the inspection result data 50 (step S111) and displays it in association with the area or division of the three-dimensional image (step S113). The operation menu may be displayed by right-clicking the mouse, or may be displayed by long-pressing on the touch panel.

For example, when the measured value information is the image data of the infrared camera, the display processing unit 102 reads the image data from the storage device 20 and superimposes and displays it on the position of the region or division of the three-dimensional image. Alternatively, when the measured value information is text data, the display processing unit 102 opens a separate window in the vicinity of the area or division to display the text data, or displays a balloon from the position of the area or division. Text data may be displayed in it.

In another example, the inspection item may be selected from the menu first, and then the position of the structure may be selected. In that case, the display processing unit 102 refers to the management table 52 to specify the area or division ID of the structure in which the selected inspection item (inspection ID) is stored, and only the area or division can be selected. 3D image may be displayed. For example, it is possible to make the operator recognize that the selectable area or division can be selected by displaying the area or division in different colors or highlighting the area or division. By not changing the display for the area or category where there is no inspection result information of the inspection item, the operator can recognize that there is no inspection result information in the area or category. The color change and highlight display may be performed when the mouse cursor is superimposed on the area or division by an operator operation (so-called mouse over operation).

In addition, the display processing unit 102 may accept a plurality of selections of inspection items, or may accept selections of a plurality of areas or divisions. The display processing unit 102 may display information on all inspection items for the selected area or division. The operation menu may be displayed using a general GUI (Graphical User Interface) such as a menu list, a pull-down menu, a radio button, a check box, and a drum roll UI (User Interface).

As described above, in the present embodiment, since the display processing unit 102 superimposes and displays the first measurement result and the second measurement result acquired by different measurement methods, a plurality of measurement results acquired by different measurement methods are displayed. It is possible to comprehensively estimate the state of the concrete structure from the above, and it is possible for the manager to easily grasp the inspection result of the concrete structure.

(Second Embodiment)
The present embodiment is the same as the above embodiment except that it has a configuration in which display data is generated using measurement results having different timings and displayed on the screen. Since the concrete structure management device 100 of the present embodiment has the same configuration as the concrete structure management device 100 of the above-described embodiment of FIG. 3, it will be described with reference to FIG. The configuration of the concrete structure management device 100 of this embodiment can be combined within a range consistent with the configuration of other embodiments.

In the present embodiment, the acquisition unit 104 acquires at least the first measurement result at the first timing and the second measurement result at the second timing in the inspection of the concrete structure. The display processing unit 102 generates display data using at least the first measurement result and the second measurement result and displays them on the screen. In the present embodiment, the first measurement result and the second measurement result are generated by, for example, the same inspection device 40, but may be generated by different inspection devices 40.

The first timing and the second timing are different timings. The acquisition unit 104 may acquire measurement results at different timings by acquiring information on different dates and times from the history information of the measurement results obtained by a certain measurement method. The first timing and the second timing are exemplified below, but are not limited thereto.
(1) Timing of opening a predetermined time interval, for example, 1 year, 5 years, 10 years, etc. (2) Timing before and after repair (3) Timing at the time of completion and subsequent inspection, or timing at each inspection (4) Arbitrary timing

The first timing and the second timing may be specified by accepting the operator's selection from the operation menu or the like.

The first measurement result and the second measurement result are an analysis of image data showing at least one of the surface and shape of the concrete structure and the measured value showing at least one of the internal and external states of the concrete structure. It is at least one of the image data obtained by image processing the result.

For example, the image data is acquired by an image captured by a high-resolution camera, an image captured by an infrared camera (an image showing a measured value measured by an infrared thermography method), and 3D digital measurement using a 3D laser scanner. It was measured using at least one of an infrared thermography method, an electromagnetic wave radar method, an ultrasonic method, and a natural potential method, and a 3D image showing the shape of a concrete structure generated using the point group data. It is at least one of the images obtained by image processing the analysis result of the measured value.
The display processing unit 102 displays the difference between the first measurement result and the second measurement result on the screen in a distinguishable state.

The difference between the first measurement result and the second measurement result is, for example, the difference in the degree of progress of the deterioration of concrete one year later.
The display of the identifiable state is, for example, highlighting (shading, highlighting, blinking, animation, 3D display, etc.) or displaying in a different color in the area where the difference occurs. Further, the display data may be generated by enclosing the area where the difference is generated with a frame or adding drawing such as a comment or a mark.

The display data showing this difference is an image showing the state of the concrete structure (state such as deterioration or damage) from the image obtained by either measurement method, automatically by manual or machine learning using artificial intelligence technology. It can be generated and drawn at the corresponding portion of the three-dimensional image of the concrete structure.

The display processing unit 102 may superimpose and display the first measurement result and the second measurement result on the screen.

The display data using the first measurement result and the second measurement result in the present embodiment is obtained by image analysis of the measurement results obtained by at least one measurement method described above obtained at different timings for a specific part of the concrete structure. The two generated images (first measurement result and second measurement result) may be superposed on the region corresponding to the specific portion of the three-dimensional image of the concrete structure.

The display processing unit 102 causes the generated display data to display at least two images in an identifiable manner by at least one of the following methods.
(1) The above difference of the second measurement result is highlighted (or drawing is added or the color is changed) on the image of the first measurement result. Alternatively, the difference from the first measurement result is highlighted (or drawing is added or the color is changed) on the image of the second measurement result.
(2) The image of the first measurement result and the image of the second measurement result are automatically switched and displayed at predetermined intervals.
(3) The image of the first measurement result and the image of the second measurement result are alternately switched and displayed in response to an operator operation such as tapping or clicking.
(4) The image of the first measurement result and the image of the second measurement result are displayed side by side. When an operator operation such as enlargement, reduction, or movement is accepted for one image, the same operation is performed for other images.

Each component (FIG. 3) of the concrete structure management device 100 of the present embodiment is realized by an arbitrary combination of hardware and software of the computer 60 of FIG. 2 as in the above embodiment. When the computer program 80 is executed on the computer 60, the computer 60 is made to execute the management method for realizing the concrete structure management device 100 of the present embodiment.

The computer program 80 of the present embodiment is a procedure for displaying a two-dimensional or three-dimensional image showing a concrete structure on a screen of a computer 60 for realizing the concrete structure management device 100, at least in the concrete structure. A procedure for acquiring the first measurement result at the first timing and the second measurement result at the second timing, at least the display data is generated using the first measurement result and the second measurement result and superimposed on the screen. It is described to execute the procedure to display.

The concrete structure management device 100 of the present embodiment also operates in the same manner as the flowchart of FIG. 9 of the first embodiment. In step S13, the first execution is performed except that the acquisition unit 104 acquires at least the first measurement result at the first timing and the second measurement result at the second timing in the inspection of the concrete structure. Similar to form.

Specifically, first, the display processing unit 102 displays a three-dimensional image of the concrete structure on the screen (step S11). Next, the acquisition unit 104 acquires at least the first measurement result at the first timing and the second measurement result at the second timing in the concrete structure (step S13). Then, the display processing unit 102 generates display data using at least the first measurement result and the second measurement result, and superimposes the display data on the screen (step S15).

In step S11, the display processing unit 102 receives an instruction to display an infrared image before and after repair by operating an operation menu or the like while displaying a three-dimensional image of the concrete structure. The display processing unit 102 synthesizes the infrared image before repair into a three-dimensional image as the first measurement result, and synthesizes the infrared image after repair into the three-dimensional image as the second measurement result. Then, the display processing unit 102 displays the two composite images side by side. The display processing unit 102 may receive information indicating that the outer wall has been selected from the three-dimensional image by the operator, and may synthesize only the infrared image of the selected outer wall into the three-dimensional image.

As described above, the operator can select which area of the concrete structure to display the measurement result. At least a part of the concrete structure in the three-dimensional image is selected by the operation of the operator, and the display processing unit 102 accepts the selected area. Further, the designation of the first timing and the second timing may also be selected by the operator from the operation menu or the like. The reception unit (not shown) may receive the timing selected by the operator, and the acquisition unit 104 may acquire the measurement result of the received timing.

As described above, according to the present embodiment, the inspection result of the concrete structure can be easily grasped by the manager as in the above embodiment, and the measurement results acquired by the acquisition unit 104 at different timings can be used. Since the screen is displayed by the display processing unit 102, it is possible to confirm the secular change of the deterioration and damage status of the concrete structure. For example, future changes can be accurately estimated from aging of concrete structures, and repair schedules can be appropriately planned.

(Third Embodiment)
The present embodiment is described above except that each of the first or second embodiments has a specific configuration for aligning the first measurement result, each image showing the second measurement result, and the three-dimensional image. It is the same as the embodiment. Since the concrete structure management device 100 of the present embodiment has the same configuration as the concrete structure management device 100 of the above-described embodiment of FIG. 3, it will be described with reference to FIG. The configuration of the concrete structure management device 100 of this embodiment can be combined within a range consistent with the configuration of other embodiments.

The first measurement method and the second measurement method are different from each other, and therefore each has a reference point.
The display processing unit 102 uses the difference between the reference point of the first measurement method and the reference point of the second measurement method to show the structure of the concrete structure for the first measurement result and the second measurement result (three-dimensional image). Align it above and display it on the screen.

Similarly, the images of the first measurement result and the second measurement result at different timings also have reference points.
The display processing unit 102 aligns the first measurement result and the second measurement result on an image showing the structure of the concrete structure and displays them on the screen by using the difference between the reference points.

As an example, a mark (for example, hitting a pin) is placed at a place that serves as a reference point of a concrete structure, and the mark is placed at the first measurement method and the second measurement method, or at the first timing and the second timing. Image to include. In addition, a three-dimensional image of the concrete structure is also generated by marking the same place. The positions are aligned by matching the positions of the marks of the obtained first measurement results and the marks of the second measurement results with the marks of the three-dimensional image. As the mark, it is preferable to use a member that is imaged in any of the different measurement methods.

The reference point for marking may be a predetermined position of the steel frame in the arrangement of the steel frame inside the concrete structure obtained by the electromagnetic wave radar. Alternatively, a specific portion of the concrete structure, for example, a pillar, a corner, a seam, a fitting, or the like may be marked and used as a reference point, or the specific portion itself may be used as a reference point for alignment.

The position indicated by the measurement result (image) and the actual position may deviate depending on the surface and the inside of the concrete structure, the depth inside the concrete to be measured, or the difference in the measurement method. there is a possibility. Therefore, it may have a conversion table for correcting this deviation. The acquisition unit 104 may correct at least one of the acquired first measurement result and the second measurement result by using the conversion table.

In the image of each measurement result, information for converting the position in the image to the coordinate position in the three-dimensional image of the concrete structure to be measured may be prepared in advance. In this case, the alignment of the first measurement result and the second measurement result may be performed using the coordinate position after the conversion.
Further, in the example of displaying the image of the first measurement result and the image of the second measurement result side by side, when one of the images is enlarged or reduced or the display position is moved, the above coordinate position information is used. , The other image may also be enlarged, reduced or moved to be displayed accordingly. In this way, the information of the two measurement results can be compared and viewed.

FIG. 11 is a diagram showing an example of an image showing measurement results by three different measurement methods in a concrete structure. FIG. 11A shows a part of an image showing the first measurement result generated by synthesizing a plurality of images of the inner wall of the concrete structure taken by using a high-resolution camera. The positions (1) to (4) in each image are reference points (reference lines). FIG. 11B shows a part of an image showing the second measurement result obtained by imaging the inner wall of the concrete structure with an infrared camera and performing image processing on the analysis result of the measurement value measured by the infrared thermography method. ing. 11 (c) shows cracks, peeling, floating, peeling, defects, discoloration, deformation, cavities, wear, based on the first measurement result of FIG. 11 (a) and the second measurement result of FIG. 11 (b). A part of the image showing the third measurement result generated by manually generating an image showing the state of damage such as rust, deflection, shear, shrinkage, etc., or automatically generated by machine learning using artificial intelligence technology. Is shown.

According to the present embodiment, the inspection result of the concrete structure can be easily grasped by the manager as in the above embodiment, and images of a plurality of measurement results by different measurement methods depending on the display processing unit 102 using the reference point can be displayed. Images of multiple measurement results at different timings can be accurately aligned.

(Fourth Embodiment)
This embodiment is the same as the above embodiment except that it has a configuration for displaying the history information stored in the inspection result data 50 and the repair content data 54. Since the concrete structure management device 100 of the present embodiment has the same configuration as the concrete structure management device 100 of the above-described embodiment of FIG. 3, it will be described with reference to FIG. The configuration of the concrete structure management device 100 of this embodiment can be combined within a range consistent with the configuration of other embodiments.

The display processing unit 102 accesses the storage device 20 that stores the history information of at least one of the measurement result and the restoration content of the concrete structure, and transfers the history information of the selected portion of the concrete structure to the selected portion. Associate and display on the screen.

Further, the display processing unit 102 changes the display form in a predetermined area unit of the structure according to the accumulation period of the information including the measurement result and the repaired content based on the history information. The accumulation period indicates, for example, how many years (1 year, 2 years, 5 years, 10 years, etc.) the number (or amount) of accumulated data is, or during the inspection period. In addition, it may be information indicating the progress of the inspection (inspection not performed, inspection in progress, inspection completed, etc.). The method of changing the display form is exemplified below, but is not limited thereto.
(1) Different display colors or different patterns are superimposed and displayed on the area for each storage period.
(2) Highlight the area where the accumulation period is equal to or less than the standard.
(3) Different predetermined marks are superimposed and displayed in or near the area for each accumulation period.

FIG. 12 is a diagram showing an example of a data structure of the accumulated information 56 that stores information indicating the accumulation period of the history information for each area of the structure. The stored information 56 is stored in the storage device 20, and for example, a flag indicating the presence or absence of history information for each year is associated with the structure ID and the area or division ID.

FIG. 13 is a diagram for explaining a change in the display form of the screen 200 according to the accumulation period of the history information. In the example of FIG. 13A, since the two walls (corresponding to the areas r0201 and r0202) both accumulate the history information for one year only for FY2018, the two walls are displayed in the same color. Has been done. In the example of FIG. 13B, of the two walls, the area r0211 corresponding to one wall corresponds to the wall of the other surface because the history information for two years of 2017 and 2018 is accumulated. Since the history information for one year only for the 2018 fiscal year is accumulated in the area r0212, the two walls are displayed in different colors.

In this way, the display processing unit 102 can change the display form for each area or division with reference to the accumulated information 56.

Further, in another example, the display processing unit 102 may change the display form according to the progress of the inspection (not performed, during the inspection, completion of the inspection, etc.) during the inspection period. The display processing unit 102 refers to the management table 52 and performs inspection based on conditions such as date and time information, inspection items, and the number of data of data corresponding to the area or division of the three-dimensional image displayed on the screen 200. It is determined whether the inspection has not been performed, the inspection is in progress, or the inspection has been completed. Judgment conditions can be acquired by the operator inputting inspection result information. The inspection result information may include an inspection period, an area or division to be inspected, an inspection item, a data type and the number of data to be measured, and the like. For example, it may be determined whether the inspection is not performed or the inspection is in progress based on the presence or absence of data for the inspection item. Further, it may be determined whether or not the inspection is completed during the inspection based on whether or not the necessary data is obtained for each inspection item from the conditions of the data type and the number of data that need to be measured for each inspection item. In addition, the inspection result information may include information indicating the progress of the inspection (not performed, inspecting, completed inspection, etc.). Based on the determination result, the display processing unit 102 changes the display form for each area.

As described above, in the present embodiment, the history information of the portion selected by the display processing unit 102 is displayed on the screen in association with the selected portion. Further, the display processing unit 102 changes the display form for each predetermined area of the structure according to the accumulation period of the history information. As described above, according to the present embodiment, the measurement result of the concrete structure can be easily grasped by the manager, the history information including the past information of the concrete structure can be browsed, and the accumulation period of the history information can be obtained. Since the display form is changed for each area according to the above, the operator can intuitively know how much data is accumulated in which area. Further, according to the present embodiment, since the display form can be changed for each area according to the progress of the inspection, the operator can know the progress of the inspection at a glance for each area.

(Fifth Embodiment)
FIG. 14 is a functional block diagram that logically shows the configuration of the concrete structure management device 100 of the present embodiment. The concrete structure management device 100 of the present embodiment is the same as that of the above embodiment except that it has a configuration that limits the data displayed on the screen according to the access authority of the operator. Further, the configuration of the concrete structure management device 100 of this embodiment can be combined within a range consistent with the configuration of other embodiments. The concrete structure management device 100 includes the same display processing unit 102 and acquisition unit 104 as in FIG. 3, and further includes an authority specifying unit 110.

The terminal device 30 can be used by, for example, a worker who performs inspection and repair work at the site, a manager who supervises the work, and a manager of a concrete structure requesting the work, but the same concrete structure. The information required differs depending on each position, even for those who are related to the work on objects. In addition, the information stored in the storage device 20 may include confidential information, and it is necessary to prevent such information from being inadvertently leaked to the outside. Therefore, in the present embodiment, by having the authority specifying unit 110, the data displayed on the screen 200 is restricted according to the access authority of the operator.

The authority specifying unit 110 specifies the access authority of the operator. The display processing unit 102 limits the data to be displayed on the screen 200 for specific information according to the access authority.

The concrete structure management device 100 stores the authentication information and the access authority in the storage device 20 in association with each other as the user information used when logging in to the system. The authority specifying unit 110 can specify the access authority from the authentication information input by the operator when logging in to use the service of the concrete structure management device 100 with reference to the user information.

FIG. 15 is a functional block diagram that logically shows the configuration of the concrete structure management device 100 of the present embodiment. The concrete structure management device 100 of the present embodiment is the same as any of the above-described embodiments except that the concrete structure management device 100 has a configuration for first switching the data to be displayed on the screen 200 according to the relative position of the operator with respect to the concrete structure. .. Further, the configuration of the concrete structure management device 100 of this embodiment can be combined within a range consistent with the configuration of other embodiments. The concrete structure management device 100 includes the same display processing unit 102 and acquisition unit 104 as in FIG. 3, and further includes a position information acquisition unit 120.

The position information acquisition unit 120 acquires position information for specifying the relative position of the operator with respect to the concrete structure. The display processing unit 102 switches the data to be displayed first based on the relative position.

Further, the display processing unit 102 switches the data to be displayed on the screen 200 first depending on whether the operator is outside the concrete structure or inside the concrete structure.

In the present embodiment, the image of the concrete structure displayed on the screen 200 by the display processing unit 102 is displayed according to the relative position of the operator with respect to the concrete structure. As a premise, the operator carries the terminal device 30 to a place of the structure, displays a three-dimensional image of the concrete structure on the screen 200 of the terminal device 30 at the place, and the concrete structure management device 100 provides the terminal device 30. Use the service.

The terminal device 30 is a portable terminal, for example, a tablet terminal 30b, a smartphone, a notebook computer 30a, and the like, and includes a position information acquisition means in addition to the configuration described with reference to FIG. The location information acquisition means is at least one of a GPS receiver, a mobile phone communication unit, and a wireless LAN communication unit. The position information acquisition unit 120 uses the position information acquisition means of the terminal device 30, for example, GPS (or quasi-zenith satellite positioning system) position information, position registration information of a mobile phone base station, and access point position of wireless LAN communication. Get at least one of the information. The position information acquisition unit 120 may acquire a plurality of types of position information and combine them to improve the accuracy of the position information.

Further, the terminal device 30 includes at least one such as an acceleration sensor, a gyro sensor, and a geomagnetic sensor, and the position information acquisition unit 120 uses the information of these sensors to display the terminal device 30 held by the operator. Further determine the orientation of. Then, assuming that the operator is facing the structure while holding the terminal device 30 in his hand and looking at the display, the position information acquisition unit 120 further determines that the operator faces the structure according to the determined orientation of the display. Determine which position you are standing in and in which direction you are facing. In this way, the position information acquisition unit 120 acquires the operator's relative position with respect to the concrete structure.

The display processing unit 102 changes the location and orientation of the three-dimensional image displayed on the screen 200 based on the operator's relative position with respect to the concrete structure, that is, according to the position and orientation of the operator standing with respect to the structure. To do. For example, when the operator is in a living room in the building, the display processing unit 102 displays a three-dimensional image of the living room on the screen 200. Then, the display processing unit 102 causes the screen 200 to display a location aligned with the direction in which the terminal device 30 is directed while the operator holds the terminal device 30 in his hand and looks at the screen 200. That is, when the operator points the terminal device 30 toward the ceiling (the surface of the display faces downward), the display processing unit 102 causes the screen 200 to display a three-dimensional image of the ceiling of the living room. When the operator points the terminal device 30 toward the floor (the surface of the display faces upward), the display processing unit 102 causes the screen 200 to display a three-dimensional image of the floor of the living room.

The display processing unit 102 further identifies the area or division of the concrete structure to which the operator faces from the position information, and selects the data to be first displayed on the screen 200 based on the area or division. .. As described above, the corresponding accumulated information differs depending on the area or division. For example, the inspection items and repair contents differ depending on whether the structure is a ceiling, a wall, or a floor, and the type of information required by the operator also differs. In addition, since the type of target structure changes depending on whether the operator is outside the structure or inside the structure, the inspection items and repair contents are different, and the type of information required by the operator is also different. different.

Therefore, the display processing unit 102 selects and displays the data to be displayed first based on the relative position between the concrete structure and the operator. Further, when the operator moves and the relative position with respect to the concrete structure changes, the display processing unit 102 switches the data to be displayed first based on the relative position of the movement destination.

Here, the "first" is one of the following.
(1) From after the three-dimensional image of a certain area or section of the concrete structure is displayed on the screen 200 to before accepting the operation from the operator for the area or section (2) The operator's operation for the area or section is performed. After accepting for the first time

In the latter case (2), the display processing unit 102 displays an external image of the concrete structure as a three-dimensional image based on the relative position of the operator with respect to the concrete structure, and when the operator selects an area, the measurement result or the measurement result regarding the area or Display the data of the repair contents. At this time, the display processing unit 102 switches the data type of the measurement result or the repair content to be displayed according to the relative position of the operator.

In the case of the former (1), the display processing unit 102 selects the data type to be displayed for each area or division and first displays it on the screen 200. The data display after the operator operates the area to display other information may be selected, for example, by setting the operator. That is, when the area is displayed on the screen 200 again after the area is removed from the screen 200, the display of the data changed by the operator operation is maintained, or the data type is set by default and is displayed first. It may be configured so that it can be set whether to return and display it.

FIG. 16 is a diagram showing an example of the data structure of the display data table 58. The display data table 58 of FIG. 16A stores the position information and the data type to be displayed first in the position information in association with each other. Here, the data type is, for example, at least one of an inspection ID indicating an inspection item, a repair item ID indicating a repair content, or data type information indicating a separately defined data type. The display processing unit 102 refers to the display data table 58, acquires a data type corresponding to the position information acquired by the position information acquisition unit 120, for example, an inspection ID, and refers to the management table 52 to obtain a structure ID and an area. Alternatively, the division ID, the position information, and the data ID corresponding to the inspection ID can be acquired, and the measured value corresponding to the data ID can be read from the inspection result data 50 and displayed on the three-dimensional image.

FIG. 16B is a diagram showing another example of the data structure of the display data table 58. In this example, in addition to the location information, the structure ID and the area or division ID are further included. The display data table 58 may store the data type corresponding to at least one of the structure ID, the area or division ID, and the position information in association with each other. The display processing unit 102 can specify the data type corresponding to at least one of the structure ID, the area or division ID, and the position information from the display data table 58. For example, when the operator has input information for identifying the structure in advance, the data type corresponding to the structure ID may be acquired and displayed first.

Further, the display processing unit 102 may switch the data to be displayed on the screen depending on the magnification of the display.

The three-dimensional image of the concrete structure displayed on the screen 200 can be enlarged or reduced according to the operation of the operator. The display processing unit 102 accepts, for example, a pinch-out or focus-in operation to the touch panel. The display processing unit 102 enlarges or reduces the three-dimensional image according to the operation of the operator.

When the magnification is greater than or equal to the first reference (small), the display processing unit 102 displays an image of the appearance of the concrete structure on the screen, and the magnification is greater than or greater than the first reference (medium). In the case of the magnification of, an image (crack, etc.) showing the damage of the concrete structure is displayed on the screen, and in the case of the magnification of the third standard (large) or more, which is larger than the second standard, the diagnosis of the concrete structure is made. An image showing the analysis result is displayed on the screen 200.

FIG. 17 is a diagram showing another example of the data structure of the display data table 58. The display data table 58 stores a plurality of data types corresponding to at least one of the structure ID, the area or division ID, and the position information in association with each other. A plurality of data types are ranked (data types 1, 2, 3, etc.). The ranking is associated with, for example, a reference value of the magnification (first reference, second reference, third reference). The reference value of the magnification may be in the range of the magnification. In this example, three reference values are used, but the number of reference values is not limited to three and may be less than three or three or more. Moreover, the standard of the reduction ratio may be set.

Here, for example, when the enlargement magnification is the first standard or more (for example, the same magnification), the data type 1, when the enlargement ratio is the second standard or more (10 times), the data type 2 and the enlargement ratio are the third standard. In the case of (10 to 100 times), it can be defined as data type 3 or the like.

In the display data table 58, the data type 1 is image data of the appearance of the concrete structure. Data type 2 is image data obtained by imaging data indicating damage to a concrete structure, for example, cracking, peeling, floating, peeling, chipping, discoloration, deformation, cavity, wear, rust, deflection, shearing, shrinkage, etc. Includes images showing the state of damage to the concrete. Data type 3 is image data showing the results of diagnostic analysis of the concrete structure, for example, an image captured by an infrared camera, an image showing the result of reinforced corrosion diagnosis by natural potential measurement, an image showing the result of deterioration diagnosis by ultrasonic exploration, and the like. Includes images showing the arrangement of reinforcing bars by electromagnetic wave radar.

The work of imaging data indicating damage of data type 2 may be created by an operator based on images showing various measurement results, or is automatically created by machine learning using artificial intelligence technology. May be done.

When the operator magnifies and displays a certain area on the three-dimensional image of the concrete structure, the measurement result and the information of the repair contents displayed can be switched according to the magnifying magnification. For example, the display processing unit 102 causes the screen 200 to display a three-dimensional image of the appearance of the outer wall of the concrete structure at a magnification of less than the second reference while displaying at the same magnification. Then, when the operator performs an enlargement operation and the enlargement magnification exceeds the second reference, the display processing unit 102 superimposes and displays an image of cracks on the outer wall. Further, when the operator performs an enlargement operation and the enlargement magnification exceeds the third reference, the display processing unit 102 enlarges the three-dimensional image and switches the cracked image to the image captured by the infrared camera in the area to superimpose and display the image. ..

When the third criterion is exceeded, the data type to be displayed may be selected according to the data type according to the area in combination with the display data table 58 of FIG. 16B.

The data type to be displayed according to the magnification and the order thereof may be set by the operator from the setting menu. The set data types and their ranks are stored in the display data table 58.

If another area is displayed on the screen 200 after the first displayed data type in a certain area is selected, the already displayed data type is inherited or newly displayed. The area of may be switched to the first displayed data type based on magnification or area. These selections may be set by the operator.

Further, the display processing unit 102 sets the damage level of the concrete structure to be displayed on the screen 200 according to the magnification. Here, the damage level of the concrete structure is a damage level that can be discriminated from the measurement result, and includes, for example, the degree of cracking of the outer wall, the depth and type of discoloration, the area of the discoloration range, the corrosion level, and the like.

For example, a crack image of an outer wall of a structure is created by detecting an image of the appearance of the outer wall. The size of the crack is divided into two levels. Specifically, the damage level is divided according to whether or not the image at the same magnification can be visually recognized. For example, a crack having a size that can be visually recognized is set to the first level, and a crack having a size that cannot be visually recognized is set to the second level.

The cracked image may be created manually by the operator, or may be automatically created by machine learning using artificial intelligence technology.

FIG. 18 is a diagram for explaining switching of display of images of cracks on the outer wall. As shown in FIG. 18A, when the enlargement magnification exceeds the second reference, the display processing unit 102 first superimposes and displays the first-level crack image on the three-dimensional image of the concrete structure of the screen 200. Next, as shown in FIG. 18B, when the enlargement ratio becomes larger than the second reference, for example, the display processing unit 102 becomes equal to or higher than the fourth reference between the second reference and the third reference. In this case, in addition to the first-level crack (L1) image, the second-level crack (L2) image is superimposed and displayed on the three-dimensional image of the concrete structure of the screen 200.

As described above, in the present embodiment, the position information acquisition unit 120 acquires the position information that specifies the relative position of the operator with respect to the concrete structure, and the data to be initially displayed on the screen is switched based on the relative position. .. As described above, according to the present embodiment, the measurement result and the repair contents of the concrete structure can be easily grasped by the administrator, and the operator can browse and work on the screen of the system at the site of the concrete structure. Since it is possible to appropriately provide information corresponding to the location of the operator, the operator can efficiently access the necessary information.

Further, in the present embodiment, the display processing unit 102 switches the data to be displayed according to the magnification of the screen display. In particular, in the present embodiment, the display processing unit 102 performs an external image of the concrete structure, an image showing damage, and an image showing the results of diagnostic analysis according to the first, second, and third criteria of the magnification, respectively. Is switched and displayed. As described above, according to the present embodiment, the content of the displayed image can be switched stepwise according to the enlargement operation of the operator, so that the operability is good.

Further, in the present embodiment, for example, the damage level of the image to be displayed is set according to the operator's screen enlargement operation (pinch out, etc.). For example, in the case of an image showing the state of cracks on the outer wall, when the magnification becomes larger than the reference, the image showing the state of rough cracks is switched to the image showing the state of finer cracks. As described above, according to the present embodiment, the damage level of the data displayed on the screen can be switched according to the intuitive operation of the operator, so that the operability is good.

FIG. 19 is a functional block diagram that logically shows the configuration of the concrete structure management device 100 of the present embodiment. The concrete structure management device 100 of the present embodiment is the same as any of the above-described embodiments except that it has a configuration for outputting an alarm of information regarding the management of the concrete structure. Further, the configuration of the concrete structure management device 100 of this embodiment can be combined within a range consistent with the configuration of other embodiments. The concrete structure management device 100 includes the same display processing unit 102 and acquisition unit 104 as in FIG. 3, and further includes a monitoring unit 130 and an alarm output unit 132.

The monitoring unit 130 monitors whether or not the information regarding the management of the concrete structure satisfies the alarm standard based on the first measurement result and the second measurement result. The alarm output unit 132 outputs an alarm when the alarm standard is satisfied.

Alarm criteria can be set for each structure or area or division and / or for each inspection or repair item. The alarm standard is preferably set by the operator, and may be set by opening the setting menu on the terminal device 30. The alarm reference may include a plurality of levels, and the form of the alarm may be changed so that different outputs are output depending on the level.

The form of the alarm output is exemplified below, but is not limited thereto.
(1) The image corresponding to the area or division in which the alarm is detected is highlighted or blinked on the screen 200. Alternatively, an icon indicating the occurrence of the alarm is displayed near the place where the alarm occurs. When the icon is operated, detailed information on the contents of the alarm is displayed.
(2) Display a message in a pop-up window notifying that an alarm has occurred. Furthermore, when the operation button or icon in the window is operated, detailed information on the content of the alarm is displayed.
(3) The LED (Light Emitting Diode) indicator provided in the terminal device 30 is blinked and lit. The alarm level may be distinguished by the blinking color, pattern, or the like.
(4) A voice message or a warning sound notifying that an alarm has occurred is output from the speaker of the terminal device 30. Alternatively, a voice output device installed in the work site is made to output voice by wireless communication such as Bluetooth.
(5) Send a message to a predetermined destination (email address, telephone number, etc.). The message sent to the mobile phone may be voice.
(6) Information (for example, a message, an icon, etc.) indicating the occurrence of an alarm is displayed on a screen 200 (for example, a neutralization depth graph of FIG. 20 described later) showing the content of the measurement result.
(7) Display or print out the alarm occurrence history information on the screen.

As an example of monitoring by the monitoring unit 130, monitoring of the start time of concrete corrosion will be described. Corrosion of concrete is cited as one of the causes of neutralization of concrete. Therefore, the monitoring unit 130 determines whether or not the residual neutralization thickness is equal to or less than the reference value based on the measurement results of the concrete cover thickness and the neutralization depth of the concrete structure, and the neutralization residual thickness is determined. When it becomes less than the standard value, it is judged that the concrete corrosion start time.

FIG. 20 is a diagram showing an example of an indicator 210 indicating the neutralization residual thickness of concrete displayed on the screen 200.
The neutralization depth is shown in a graph (indicator 210) with the cover thickness of the concrete structure as the horizontal axis. Two reference values are used as the criterion values for determining the corrosion start time. The alarm output unit 132 notifies when the neutralization depth exceeds the first reference value 212, and outputs an alarm in which the neutralization depth exceeds the second reference value 214.

In the example of FIG. 20A, the value of the neutralization depth graph 216a is less than the first reference value. In the example of FIG. 20B, the value of the neutralization depth graph 216b exceeds the first reference value 212. Therefore, the alarm output unit 132 notifies the user that the neutralization depth exceeds the first reference value 212. In the example of FIG. 20 (c), the value of the neutralization depth graph 216c exceeds the second reference value 214. Therefore, the alarm output unit 132 outputs an alarm indicating to the user that the neutralization depth exceeds the second reference value 214.

Further, the graph 216a, the graph 216b, and the graph 216c may be displayed in different colors. For example, assuming that graph 216a is green, graph 216b is yellow, and graph 216c is red, the operator can intuitively recognize the danger level. Alternatively, the graph 216a may be a normal display, the graph 216b may be a display of a slow blinking interval of a predetermined speed or less, and the graph 216c may be a display of a blinking interval faster than the graph 216b.

Further, in the example of FIG. 20 (d), a graph 218 is shown so that the progress of neutralization for each inspection period can be understood. In the graph 218, the measurement results of this time, the previous time, and the time before the previous time are displayed together so as to be distinguishable. The display processing unit 102 uses the history information to display a graph using the measurement results performed a plurality of times in the past. As shown in FIG. 20D, the values up to the previous time, the values up to the previous time, and the values this time may be displayed in different display forms (display color, pattern, emphasis, blinking, etc.), or simply lines. It may be displayed separated by. Further, the graph 216a of FIG. 20 (a), the graph 216b of FIG. 20 (b), and the graph 216c of FIG. 20 (c) may be displayed side by side in close proximity to each other. Further, in FIG. 20D, labels of "this time", "previous time", and "previous time" are shown, but information on each inspection date and time (for example, information such as the year) is displayed on the graph 218. May be good. Furthermore, the detailed contents of each inspection may be displayed according to the required operation of the operating system.

By doing so, it is possible to confirm the progress of neutralization together with past information even before the corrosion start time arrives, so that it is possible to formulate an appropriate repair plan and implement countermeasures without missing the countermeasure time.

As described above, in the present embodiment, the monitoring unit 130 monitors whether or not the information regarding the management of the concrete structure satisfies the alarm standard, and if the alarm standard is satisfied, the alarm output unit 132 outputs an alarm. As described above, according to the present embodiment, the measurement result and the restoration content of the concrete structure can be easily grasped by the manager, and the alarm can be monitored based on the measurement result and the restoration content information, and also in the past. Since the results of several measurements can be displayed together, it is possible to catch the signs of a problem in advance before it occurs, and take appropriate measures at an early stage.

The advice output unit 140 outputs advice information according to the conditions. Further, the advice information may be configured to output information corresponding to a standard condition, or may be configured to notify a person who gives advice of information indicating that it is necessary to output the advice information. The person who received the notification may accept the registration of the advice information created and notify the target person who should be notified of the pre-registered advice. In addition, the model information necessary for creating the advice information may be provided to the person who gives the advice.

The output form of the advice information is exemplified below, but is not limited to these.
